A flexible tube (12A) for an endoscope is formed from a helical tube (32) formed with a strip-shaped member wound in a helical shape, and a mesh tube (34) at the outer periphery of the helical tube, the mesh tube having a ring-shaped cross-section and being formed from braided fine wires. A thermoplastic resin (35) is formed in a patterned shape at the outer periphery of the mesh tube, and an outer skin (36) is formed at the outer periphery of the mesh tube, over the thermoplastic resin, from a material that has a smaller thermal deformation than the thermoplastic resin. The flexible tube of the endoscope is not readily thermally deformed and is not readily imparted with a permanent or semi-permanent curvature during autoclave processing.
